Isolation of Modern Music

I'm not sure if someone mentioned this during class or how I started thinking about this idea but I thought it was interesting the drastic change between the way music used to be more social than it is today. Today's music is more personalized, especially with the emergence of iPods. With sheet music and pianos being played in parlors, it was family event of entertainment and it was a way of bringing the family together. When we were shown clips of dances such as the fox trot, it was made into a social event where you had interactions with one another. Today, people are in isolation as they listen to mp3 players. People do go to concerts, but it isn't a social event and very rarely do you actually meet people, you are there to watch and enjoy the band. The most interaction you have with people is not in a friendly way (or is it?), but a pushing and shoving and maybe a few punches here and there. The only example I can think of where music actually brings people together is within a club like setting. I think it is more acceptable for people to dance and to talk to people they don't know and wouldn't normally interact with. I'm not sure why, but a lot of the time people stay in their little groups of friends when they go to concerts and don't interact with other people in the crowd. I just thought that the difference between the role of music now and then was rather interesting.
